We're dividing 712703 by 72 
The aim is to understand the frequency of 72 in 712703.

Step 1:
The number 72 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 72

Going ahead to step 2:
The number 72 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 72

Going ahead to step 3:
72 goes into 712 9 times with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 64 after subtracting 648 from 712.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 72

Advancing to step 4:
If we divide 647 by 72, we get 8 and a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we subtract 576 from 647, we get 71.
Include the next digit (0) from the dividend after 71, then repeat: 710 / 72

On to step 5:
710 divided by 72 is 9 with a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 989.0
Deduct 648 from 710 and we're left with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 72

Advancing to step 6:
72 can be fit into 623 8 times, resulting in a remainder of 47.
The next digit of our result is 8. 
Result so far: 9898.0
The remainder is 47 after subtracting 576 from 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
470 divided by 72 is 6 with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 9898.6
If we subtract 432 from 470, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
380 divided by 72 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 9898.65
Subtracting 360 from 380 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 72 fits into 200 2 times, leaving a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 9898.652
If we take 144 away from 200, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
72 goes into 560 7 times with a remainder of 56.
The next digit of our result is 7. 
Result so far: 9898.6527
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 9898.65277
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 9898.65277 with a remainder of 5.6e-05.
